活动断层粘滑错动条件下地铁隧道结构的受力特性分析

为探明拟建的乌鲁木齐轨道交通1号线在主城区通过九家湾断层粘滑错动条件下地铁隧道结构的受力特性，基于断层形成机制与连续介质分析方法，建立表征围岩与支护结构共同变形关系的地层结构模型，研究不同构造条件下隧道衬砌结构横向内力分布、纵向受迫影响效应，分析整体式隧道衬砌结构的内力、变形及塑性区分布规律。

Analysis on Mechanical Characteristics of Subway Tunnel Structures under Stick-slip Movement in Active Faults

To explore the mechanical characteristics of the subway tunnel under stick-slip movement in Jiujiawan fault which Urumqi Metro Line 1 passed through in the main city, in this paper, based on the fault formation mechanism and continuous medium analysis method, the stratigraphic model representing the common deformation relationship of surrounding rock and supporting structure is established, under different tectonic conditions, tunnel lining structure transverse internal force distribution and longitudinal forced effect is studied; and the internal force, deformation and plastic zone distribution of integral tunnel lining structure are analyzed.
